This watch is based on a 1957 pattern and combines vintage design with modern advancements. It features a box sapphire crystal that closely resembles the original plexiglass crystal. The movement is a sophisticated Ronda R 150 or equivalent, boasting 25 jewels and a frequency of 28,800 vibrations per hour (4Hz). This precision-crafted powerhouse offers a substantial 38-hour power reserve, ensuring reliable performance. Notably, it is equipped with hacking and hand-winding capabilities, exemplifying both efficiency and convenience.
The watch uses Luminova instead of Tritium, which was used in the 1950s. The main advantage of Luminova is that it does not deteriorate with age and is non-radioactive. The luminous paint color on this variant is identical to the original 1950s models.

Benefits of Sapphire Crystal
Many people ask about the advantages of sapphire crystal over the original plexiglass. Synthetic sapphire is the superior material for watch crystals due to its exceptional strength and resistance to shattering and scratching. These qualities make it highly appealing to military and security personnel, police officers, and individuals with active outdoor lifestyles—groups that make up over 70% of our customers.
The original plexiglass crystals, made from plastic/acrylic materials used in the 1960s, were prone to scratches and cracks and limited the watch’s water resistance. In over 90% of cases where clients experience cracked crystals, the watches have mineral glass or plexiglass. Even hardened mineral crystals do not match sapphire's durability under harsh conditions.
Sapphire crystals are strong because they are heat-treated to remove internal stresses, which can cause weakness. The crystals are then made into watch faces and coated with two layers of anti-reflective material. Interestingly, sapphire crystal is now also used in the latest iPhones. Despite its higher cost, sapphire crystal's superior quality justifies its use in higher-end watches.
